首先是針對防火特性上，不管是柔性的YTTW礦物電纜還是剛性的BTTZ電纜，兩者的存在都是為了保證電纜在一定的火焰以及高溫下能夠保證電纜的正常運作，所以它們的防火性能都是極為不錯的。但是從高溫的狀態來講，柔性的YTTW礦物電纜能夠承受的極限溫度為1083攝氏度，而剛性BTTZ電纜只有1000攝氏度，并且柔性YTTW礦物電纜能夠在950在1000攝氏度高溫中運行3小時，BTTZ電纜只能維持半小時而已。然后是區分電纜的制作長度，因為工藝特性原因。YTTW礦物電纜因為比較柔和一些，在制作的時候能夠將其長度鋁芯電纜延(yan)伸1000米都(dou)是沒有問(wen)題的(de)(de)，而(er)剛性BTTZ電(dian)纜(lan)需要考慮過長的(de)(de)電(dian)纜(lan)不易(yi)存放，并且不容(rong)易(yi)生產制作，所(suo)以(yi)YTTW礦物電(dian)纜(lan)能(neng)夠避免長度要求的(de)(de)規范，不用(yong)(yong)擔心(xin)使用(yong)(yong)的(de)(de)時(shi)候長度不足使用(yong)(yong)接口。

1. 看電纜電線長度：福建性價比鋁芯電纜國家(jia)標(biao)準規定，電(dian)(dian)線電(dian)(dian)纜每卷100米，計量誤(wu)差(cha)不大于0.5%，也就是(shi)(shi)每卷線的長度(du)為100±0.5米，但是(shi)(shi)有(you)(you)些商(shang)(shang)家(jia)標(biao)注的是(shi)(shi)100±20米，但實(shi)際(ji)上，卻(que)只(zhi)有(you)(you)80米左右。2. 看電(dian)(dian)阻值(zhi)(zhi)：電(dian)(dian)阻值(zhi)(zhi)超標(biao)的話，電(dian)(dian)線就容(rong)易出(chu)現(xian)溫度(du)過高、老化的危險，而且如果(guo)電(dian)(dian)線短路(lu)(lu)的話，還(huan)會(hui)引發火災。并且電(dian)(dian)阻值(zhi)(zhi)超標(biao)，還(huan)增加(jia)傳輸電(dian)(dian)量時的消耗，增加(jia)電(dian)(dian)費，所以，我們在(zai)選擇時，一定要(yao)留意這一點(dian)。3.看原(yuan)材(cai)料(liao)：純銅(tong)芯的材(cai)料(liao)導電(dian)(dian)性好(hao)，而且不易老化，更加(jia)耐用(yong)，也減少了故障發生。但是(shi)(shi)有(you)(you)些商(shang)(shang)家(jia)，會(hui)在(zai)銅(tong)材(cai)質(zhi)中(zhong)添加(jia)一些雜質(zhi)銅(tong)、回收銅(tong)，還(huan)有(you)(you)的劣質(zhi)產品通過降低銅(tong)芯實(shi)際(ji)截面積(ji)，來(lai)減少銅(tong)材(cai)質(zhi)的用(yong)量，這樣(yang)容(rong)易導致電(dian)(dian)線電(dian)(dian)纜用(yong)電(dian)(dian)過程中(zhong)發熱(re)，損壞外邊的絕(jue)緣層(ceng)塑料(liao)，容(rong)易讓電(dian)(dian)線老化，導致出(chu)現(xian)漏電(dian)(dian)、短路(lu)(lu)的問(wen)題。
